lifted on a jack is dangerous. If the
vehicle slips off the jack, you could
be badly injured or killed. Never get
under a vehicle when it is
supported only by a jack.
{Warning
Raising the vehicle with the jack
improperly positioned can damage
the vehicle and even make the
vehicle fall. To help avoid personal
injury and vehicle damage, be sure
to fit the jack lift head into the
proper location before raising the
vehicle.
{Warning
Lifting a vehicle and getting under
it to do maintenance or repairs is
dangerous without the appropriate
safety equipment and training. If a
jack is provided with the vehicle, it(Continued)

is designed only for changing a flat
tire. If it is used for anything else,
you or others could be badly injured
or killed if the vehicle slips off the
jack. If a jack is provided with the
vehicle, only use it for changing a
flat tire.
Caution
Using a jack to raise the vehicle
without positioning it correctly
could damage your vehicle. When
raising your vehicle on a jack, be
sure to position it correctly under
the frame and avoid contact with
the plastic molding.5. Turn the wheel wrench clockwiseto raise the jack lift head until the
slots in the jack head fit into the
metal flange behind the cut out on
the plastic molding. Do not raise
the vehicle yet.
6. Put the compact spare tire near you.
7. Raise the vehicle by turning the jack handle clockwise. Raise the
vehicle far enough off the ground
so there is enough room for the
road tire to clear the ground.

off, causing a crash.
12. Reinstall the wheel nuts. Tighten each nut by hand until the wheel is
held against the hub.
13. Lower the vehicle by turning the jack handle counterclockwise.
{Warning
Wheel nuts that are improperly or
incorrectly tightened can cause the
wheels to become loose or come off.
The wheel nuts should be tightened
with a torque wrench to the proper
torque specification after replacing.

supplied by the aftermarket
manufacturer when using accessory
locking wheel nuts. See Capacities
and Specifications 0394 for original
equipment wheel nut torque
specifications.

can lead to brake pulsation and
rotor damage. To avoid expensive
brake repairs, evenly tighten the
wheel nuts in the proper sequence
and to the proper torque
specification. SeeCapacities and
Specifications 0394 for the wheel
nut torque specification.
14. Tighten the wheel nuts firmly in a crisscross sequence, as shown. 15. Lower the jack all the way and
remove the jack from under the
vehicle.

Wheel covers will not fit on the
vehicle's compact spare. If you try
to put a wheel cover on the
compact spare, the cover or the
spare could be damaged.
{Warning
Storing a jack, a tire, or other
equipment in the passenger
compartment of the vehicle could
cause injury. In a sudden stop or
collision, loose equipment could
strike someone. Store all these in

Compact Spare Tire
{Warning
Driving with more than one
compact spare tire at a time could
result in loss of braking and
handling. This could lead to a crash
and you or others could be injured.
Use only one compact spare tire at
a time.
If this vehicle has a compact spare
tire, it was fully inflated when new;
however, it can lose air over time.
Check the inflation pressure regularly.
It should be 420 kPa (60 psi). Stop as soon as possible and check
that the spare tire is correctly inflated
after being installed on the vehicle.
The compact spare tire is designed for
temporary use only. The vehicle will
perform differently with the spare tire
installed and it is recommended that
the vehicle speed be limited to
80 km/h (50 mph). To conserve the
tread of the spare tire, have the
standard tire repaired or replaced as
soon as convenient and return the
spare tire to the storage area.
When using a compact spare tire, the
AWD (if equipped), ABS, and Traction
Control systems may engage until the
spare tire is recognized by the vehicle,
especially on slippery roads. Adjust
driving to reduce possible wheel slip.
Caution
When the compact spare is
installed, do not take the vehicle
through an automatic car wash
with guide rails. The compact spare
can get caught on the rails which
can damage the tire, wheel, and
other parts of the vehicle.
Do not use the compact spare on
other vehicles.
Do not mix the compact spare tire or
wheel with other wheels or tires. They
will not fit. Keep the spare tire and its
wheel together.
Caution
Tire chains will not fit the compact
spare. Using them can damage the
vehicle and the chains. Do not use
tire chains on the compact spare.

cover to expose the terminal.1. Check the other vehicle. It must have a 12-volt battery with a
negative ground system.
Caution
If the other vehicle does not have a
12-volt system with a negative

9. Start the engine in the vehicle withthe good battery and run the
engine at idle speed for at least
four minutes.
10. Try to start the vehicle that had the discharged battery. If it will not
start after a few tries, it probably
needs service.
Caution
If the jumper cables are connected
or removed in the wrong order,
electrical shorting may occur and
damage the vehicle. The repairs
would not be covered by the vehicle
warranty. Always connect and
remove the jumper cables in the
correct order, making sure that the
cables do not touch each other or
other metal.
Jumper Cable Removal
Reverse the sequence exactly when
removing the jumper cables.
After starting the disabled vehicle and
removing the jumper cables, allow it
to idle for several minutes.
Towing the Vehicle
Caution
Incorrectly towing a disabled
vehicle may cause damage. The
damage would not be covered by
the vehicle warranty. Do not lash or
hook to suspension components.
Use the proper straps around the
tires to secure the vehicle. Do not
drag a locked wheel/tire. Use tire
skates or dollies under any locked
wheel/tire while loading the vehicle.
Do not use a sling type lift to tow
the vehicle. This could damage the
vehicle.
Caution
Improper use of the tow eye can
damage the vehicle. If equipped, use
the tow eye to load a disabled
vehicle onto a flatbed tow truck
from a flat road surface, or to move
the vehicle a short distance. Use
caution and low speeds. The (Continued)
Caution (Continued)
transmission must be
in (N) Neutral when moving the
vehicle.
GM recommends a flatbed tow truck
to transport a disabled vehicle. Use
ramps to help reduce approach angles,
if necessary. A towed vehicle should
have its drive wheels off the ground.
Contact Roadside Service or a
professional towing service if the
disabled vehicle must be towed.
If the vehicle is equipped with a tow
eye, only use the tow eye to pull the
vehicle onto a flatbed car carrier from
a flat road surface. Do not use the tow
eye to pull the vehicle from snow,
mud, or sand.

Front Attachment Points
The vehicle is equipped with specific
attachment points to be used by the
towing provider. These holes may be
used to pull the vehicle from a flat
road surface onto the flat bed tow
truck.
Recreational Vehicle
Towing
Recreational vehicle towing means
towing the vehicle behind another
vehicle, such as behind a motor home.
The two most common types of
recreational vehicle towing are known
as dinghy towing and dolly towing.Dinghy towing is towing the vehicle
with all four wheels on the ground.
Dolly towing is towing the vehicle
with two wheels on the ground and
two wheels up on a device known as a
dolly.
Here are some important things to
consider before recreational vehicle
towing:
.Become familiar with the local laws
that apply to recreational vehicle
towing. These laws may vary by
region.
.The towing capacity of the towing
vehicle. Be sure to read the tow
vehicle manufacturer's
recommendations.
.How far the vehicle will be towed.
Some vehicles have restrictions on
how far and how long they can be
towed.
.The proper towing equipment. See
your dealer or trailering professional
for additional advice and equipment
recommendations.
.If the vehicle is ready to be towed.
Just as preparing the vehicle for a
long trip, make sure the vehicle is
prepared to be towed.
Caution
Use of a shield mounted in front of
the vehicle grille could restrict
airflow and cause damage to the
transmission. The repairs would not
be covered by the vehicle warranty.
If using a shield, only use one that
attaches to the towing vehicle.
Dinghy Towing
Caution
